Change Konqueror format to single column

I'm running Konqueror in Kubuntu 21.10. Is there a way to persuade it to do listings in a single column rather than three columns?

Update 1: Konqueror is not the only Ubuntu program with this behavior, so a general solution would be very useful. The three-column format defies easy scrolling through a long list. To see the third column, you need to scroll horizontally, which is awkward and unnatural. It also makes list selection nearly impossible.
